1. blockchain is a public account book. You can't say that your natural gas and chopsticks violate the law, because they are just tools
Chinese Mahjong: the world's earliest blockchain project
first of all, a initiates an application. I want to play mahjong and set up a mahjong Bureau, which is equivalent to creating a block, and this block will be broadcast to B, C, D, a, B, C, C, C, C, C, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D D...
in the process of playing mahjong, the above four people constantly play cards, which can be understood as mining, through what to mine? Mahjong machine can understand the mineralization machine. These four miners are the so-called miners. These four miners collide from 144 mahjong, and any right card can be Hu card. We can understand the 144 mahjong as a series of hash values (numbers). The process of Hu card is called computational power. Until Hu card, it means that the right hash value is collided and you can get a reward, Each person will pay the corresponding chips to C and put them in the blockchain. The reward is bitcoin or other virtual coins
Why do the other three people take the initiative to reward C? That's because these people have automatically reached a consensus that C has indeed won, and everyone has recorded the account, including the family members who are sitting next to buy horses. It's not good to deny it, otherwise when it comes out that the character is not good, no one will play with him again. After all, the circle is very important
when we reached a consensus, we didn't see any intermediary or third party judging that C had won, and the rewards given to C didn't need to be transferred to C through the third party. All of them were direct point-to-point transactions. This process was decentralization. The card players (miners) recorded their own achievements in the first game, and the third team won the first game, After the record is completed, a complete block is generated. But remember, this is only the first round. In the whole blockchain, this is just a node. The first eight rounds are finished, that is, eight nodes (blocks). Eight blocks are connected together to form a complete account book, which is the blockchain. Because everyone has one account book, it is a distributed account book. The purpose is to prevent someone from tampering with records. In the end, it is clear who wins or loses.

2. Elastic force can't be regarded as completely conservative force, which should be classified as well.
for example, the elastic force of spring belongs to conservative force, and if you take a rope to pull an object to move, the tension (elastic force) of the rope is not conservative force at this time.
therefore, elastic force is not completely conservative force.
non conservative force:
non conservative force has different work and path The force is called nonconservative force. The common friction force and the impact force of inelastic collision between objects are all non conservative forces. The non conservative force has the characteristic that the work along any closed path is not equal to zero. Non conservative forces include dissipative forces and non dissipative forces. In the range of mechanics, most of the non conservative forces in contact are dissipative forces, so dissipative forces have become synonyms of non conservative forces for a long time.

3.
When the spring elongation changes from XA to XB, the elastic work of mass m is
under the action of elastic force F = - KX, which shows that the elastic force is a conservative force. The work of elastic force is equal to the negative value of elastic potential energy increment
4. Is a conservative force, spring and physics together make a conservative system, the spring force is a function of the spring variable, after the path integral, you know..
5. Conservative force is divided into internal force and external force. Conservative force is a force whose work has nothing to do with the specific path, but only with the initial position. The general field force has this characteristic. Then we can see whether it is an external force or an internal force. The internal force is conservative
6. Although the centre of Hong Kong Island on Hua Lan Road belongs to the Quarry Bay area, it is closer to the Tai Koo MTR station
take the subway to Taigu station, exit b, go straight along Taigu primary school, see Kiley Road Park, turn right at the traffic light, turn left at another traffic light, and you will see an HSBC Bank. Walk over, then see Standard Chartered Bank, and then go ahead to see China Resources supermarket. Go straight along the ramp turning right at the supermarket, and you will see KFC, opposite to Hong Kong Island Center. The journey is about 15 minutes
it takes at least 25 minutes to get out of the fish stream.
